## `ik_llama.cpp` imatrix Quantizations of zai-org/GLM-4.7
*NOTE* `ik_llama.cpp` can also run your existing GGUFs from bartowski, unsloth, mradermacher, etc if you want to try it out before downloading my quants.

Some of ik's new quants are supported with [Nexesenex/croco.cpp](https://github.com/Nexesenex/croco.cpp) fork of KoboldCPP with Windows builds for CUDA 12.9. Also check for [Windows builds by Thireus here.](https://github.com/Thireus/ik_llama.cpp/releases) which have been CUDA 12.8.

These quants provide best in class perplexity for the given memory footprint.

## Big Thanks
Shout out to Wendell and the **Level1Techs** crew, the community [Forums](https://forum.level1techs.com/t/deepseek-deep-dive-r1-at-home/225826), [YouTube Channel](https://www.youtube.com/@Level1Techs)!  **BIG thanks** for providing **BIG hardware** expertise and access to run these experiments and make these great quants available to the community!!!

Also thanks to all the folks in the quanting and inferencing community on [BeaverAI Club Discord](https://huggingface.co/BeaverAI) and on [r/LocalLLaMA](https://www.reddit.com/r/LocalLLaMA/) for tips and tricks helping each other run, test, and benchmark all the fun new models! Thanks to huggingface for hosting all these big quants!

Finally, I *really* appreciate the support from [aifoundry.org](https://aifoundry.org) so check out their open source RISC-V based solutions!

## Quant Collection
*NOTE*: I'm working on some more quant recipes in the IQ2_KS-ish size range today Dec 24th...

Perplexity computed against *wiki.test.raw*.

![Perplexity Chart](images/perplexity.png "Chart showing Perplexity improving as BPW increases.")

These first two are just test quants for baseline perplexity comparison:
* `BF16` 667.598 GiB (16.003 BPW)
  - Final estimate: PPL over 565 chunks for n_ctx=512 = 3.9267 +/- 0.02423
* `Q8_0` 354.794 GiB (8.505 BPW)
  - Final estimate: PPL over 565 chunks for n_ctx=512 = 3.9320 +/- 0.02428

*NOTE*: The first split file is much smaller on purpose to only contain metadata, its fine!

## IQ5_K 250.635 GiB (6.008 BPW)
Final estimate: PPL over 565 chunks for n_ctx=512 = 3.9445 +/- 0.02439
